Solve`px+qy=p-q,qx-py=p+q`

Solve for x and y by cross-multiplication : (i)px+qy=p-q,qx-py=p+q

Solve the following pair of linear equations : px + qy= p-q qx- py= p+q

Solve the following pair of linear equations: (1) (i)ax+by=c,px+qy=p-q,qx-py=p+q0,bx+ay=1+

If lines px+qy+r=0,qx+ry+p=0 and rx+py+q=0 are concurrent,then prove that p+q+r=0 (where p,q,r are distinct )

Three lines px+qy+r=0 , qx+ry+p=0 and rx+py+q=0 are concurrent , if

The lines px+qy+r=0,qx+ry+p=0,rx+py+q=0 are concurrant then

The base BC of a hat ABC is bisected at the point (p,q)& the equation to the side AB&AC are px+qy=1&qx+py=1. The equation of the median through A is: (p-2q)x+(q-2p)y+1=0(p+q)(x+y)-2=0(2pq-1)(px+qy-1)=(p^(2)+q^(2)-1)(qx+py-1) none of these

If px^(3)+qx^(2)+rx+s=0 is a R.E .of second type then p=s,q=r p=-s,q=-r p=s,q=-r p=-s ,q=r

Show that the reflection of the line px+qy+r=0 in the line x+y+1 =0 is the line qx+py+(p+q-r)=0, where p!= -q .
